Cerebras Locks In 165 MW Wafer-Scale Data Center in Finland Under Seven-Year Contracts
Cerebras Systems (NASDAQ: CBRS) and Compute Nordic Finland announced a new AI data center in Mikkeli, Finland, scaling in three phases to 165 MW of contracted IT capacity. Construction on the initial 50 MW phase is already under way. The deal is structured as a series of service orders, each with seven-year contract terms, giving Cerebras long-duration dedicated infrastructure for its wafer-scale compute platform.
Phase Structure
| Phase | Capacity |
|---|---|
| Phase 1 (under construction) | 50 MW |
| Phase 2 | 80 MW |
| Phase 3 (full build-out) | 165 MW |
The phased approach is standard for large data center projects but the contract structure here is specific to Cerebras’s model: rather than leasing commodity rack space and deploying its chips, Cerebras is anchoring a purpose-built facility designed from the ground up for high-density wafer-scale compute.
Regional Stakes
Independent analysis from Ramboll’s Finnish Data Center Market Study estimates the full 165 MW project represents €1.0-1.7 billion in indicative regional investment, with 80-250 direct permanent jobs and €0.8-2.5 million per year in property tax revenue for Mikkeli and the South Savo region.
The facility is designed for efficiency: closed-loop cooling systems that recirculate water rather than drawing continuously from municipal supply, and infrastructure to support waste-heat recovery — converting heat generated by AI compute into usable thermal energy for the surrounding community.
Why Finland
Nordic data center infrastructure has attracted sustained capital over the past two years. Finland’s cold climate reduces cooling costs materially. Power is available at competitive rates with high renewable penetration. The Ramboll report that underpins the investment estimates was commissioned in September 2025 — Cerebras has been planning this deal for the better part of a year.
For Compute Nordic Finland, the Mikkeli project is its primary infrastructure commitment. The company leads project development, operator responsibility, and programme governance, partnering with local construction, engineering, and energy suppliers.
Cerebras’s Infrastructure Play
The Mikkeli announcement is a physical-infrastructure bet, distinct from Cerebras’s chip business. The company already has the wafer-scale engine (WSE), which integrates 2.6 trillion transistors onto a single chip larger than a dinner plate. Deploying that at scale requires purpose-built cooling and power infrastructure that commodity data centers are not designed to support.
By locking seven-year contracts in a dedicated facility, Cerebras is guaranteeing the compute environment its hardware requires and signalling long-term demand visibility to investors. The IPO filing from April 2026 cited a $20 billion OpenAI supply contract as its primary revenue anchor. Mikkeli adds a second pillar: owned or contracted capacity outside the customer concentration risk that concerned analysts at the time of the IPO.
Demand for Cerebras’s platform is still narrow compared to Nvidia-based alternatives. The bet in Mikkeli is that wafer-scale economics justify a dedicated, long-duration infrastructure commitment — and that global demand for Cerebras compute grows fast enough over the contract period to fill 165 MW.
